Yep, exactly correct.
Here's the voice of experience on the relevance of seat tube angles:
"aggressive seat tube angles -seventy four degrees- often make it impossible to move the saddle back far enough to achieve the right pedaling position....with a seat tube angle of approximately seventy two or seventy three degrees you should be fine."
